PLASTEB-BOABD TILE.

Application filed February 16, 1822. Serial No. 537,046.

To all whom it may concern.

Be it known that I Ewan) F. TnoHMnR to the accompanying drawings.

his invention relates to a plaster board r1 and the object of the invention the construction of a tile which is very durable in structure, efficient in operation, and comparative y easy to handle or place in position where the builder desires.

lVith this and other objects in. view, my i nventien comprises certain novel combina tions, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

in the drawing:

Figure is side view of a tile constructed acconlance with the present invention.

Figure 2 is a sectional view, taken on line. n2, Fig. 1, and looking 1n the directlon c of the arrows.

Figure 3 isa fragmentary, perspective view of one portion of the tile.

Figure 4 is a sectional view, taken online t Fig. 1, and looking in the direction of the arrows.

Figure 5 is a fragmentary, sectional view of another embodiment of my tile.

Referring to the drawings by numerals, 11 desi nates the side sections, 2-2 are the end sections and 3-3 are the central sections.

Each side section 1 is preferably of a rectangular shape and along its longitudinal edges are formed inwardly-extending flanges 4; these flanges are rounded at 5 on their inner faces, and these rounded faces 5 register with similar portions on the end and central sections (Fig. 3). Each end and .entral section is provided with tench-like extensions 6 at its ends, which extensions fit between the flanges 4 of the side sections 1. The side sections 1 are placed against the sections 2 and 3, and all of the sections are held together by fastening devices 7.

A suitable sheet covering 8 is attached to each side section 1, Fig. 4.

All of the fastening devices 7 are similarly constructed so it will only be necesto specifically describe one. The fastening device 7 is formed byfirst producing a transverse aperture. 9 near each end of the end and central sections. Then a single piece of wire istwisted as at 10, F ig. 4, with closed ends 11, 3, projecting sci through the side sections 1;. these looped or closed ends 11 are bent down flat upon the outer faces of side sections 1, and tacks or nails 12 are driven through the closed ends 11 and into the sections, 1 and the trans-- verse section, Fig. 4. The free endsv of the wire are threaded through the aperture 9 (Fig. 3) and then bent at right-angles, as at 13, against the inner face of the; cross piece, whether the cross piece is one of the end sections 2 or oneof the central sections 3. disposed end 13, against the cross section, securely anchors the fastening device to the section, and the threading of the wirev through the side sections and the fastening of the extended portions, by tacks or nails 12, securely ties or fastens the side and cross sections together.

I claim that my tile is lighter than any other tile; is easier to handle, thereby saving labor, cost of shipment, and means less weight on a floor; that it eliminates the cracking of plaster, which is a common fault with the ordinary tile on the market today, and thus itdoes away with a straight joint from floor to ceiling, as is the common case with the plaster board fastened to metal studding; my tile is also fire-proof.

It is to be understoodthat I am not limited to my specific kind of material for constructing the side,-end and central sections,. ash; is obvious that differentmaterials may be used, and the substitution of one material for another material does not constitute invention.

Referring to Fig. 5: In the embodiment shown in Fig. 5, the tacks or nails 12 are not driven into the sections 1 but are laid flat thereon, and by twisting the nails 12, the wire is twisted more at 10, resulting in the side pieces 2 being drawn together very tightly.

The end and central sections 2 and 3, respectively, constitute cross sections, and I use the term cross sections in the appended claims to generically specify the end and central sections.

While I have describedthe preferred embodiments of my invention, and have illus- This bending of the angularlyeach section-provided along its longitudina "edges wlth inwardly-extending flanges, end

sections and central sections between the side sections and their flanges, and fastenin means securing all ot the sections together.

2.111 a device of the class described,t he

combination of a plurality of side sections,

each side section provided with inwardlyextending flanges along their longitudinal edges, each flange being rounded on its inner face, end and central sections between said side sections, each end and central section provided with rounded ends engaging the rounded inner faces of the flanges, and means fastening all of said sections together.

8. In a device of the class described, the combination of a plurality of side sections, each'side section provided with a pair of flanges, end and central sections between said side sections, each end and central section provided with tenon-like extensions positioned between the flanges of the side sections, and means fastening all of said sections together.

4. In a device of the class described, the combination of side and cross sections, fastening devices for said side and cross sections, each fastening device provided with means extending through the side sections and fastened to tions, and said fastening device provided with ineans'extending through a cross sec tion and anchored thereto.

5. In a device of the class described, the combination of side and cross sections, tastening devices securing said side and cross the outer face of said secsections together, and each fastening device having portionsfastened toithe side sectlons and a portlon tastened to the cross section.

6. In a combination of side and cross sections, fastening devices securing said side and cross lina device of the class described, the,

combination of side and cross sections, fas tening devices securing all of the sections togather, each cross section provided with a transverse aperture, each fastening device formed from a single piece of wire having closed portions extending through the side sections, the ends of the wire threaded through'the aperture of the cross section and bent at right-angles against the inner face of the cross section, the closed ends of the Wire bent fiat against the side sections, and fastening means extending through the closed bent portionsand into the side sections securing the fastening devices to the side sections.

8. ln device of the class described, the combination of side and cross sections, each cross section provided with a pair of transverse apertures near its ends, a pair of fastening devices against the cross section contiguous to said apertures, each fastening 'device formed from a single piece of wire twisted and having closed or looped portions extending through the side sections and posttioned flat against their outer faces, means extending through the closed portions and securing the fastening devices to the side sections, and the ends of thewire being threaded through the'transverse aperture and bent at right-angles flat against the inner face of the cross section, substantially as shown and described.

in testimony whereof I hereunto my signature.
